Thanks a lot for taking on the task of herding cats.

Here are some comments:
  - Growing complexity does not have to mean worse performance.  It
really depends
   on where the complexity resides. 
I'll restore "may" here. 
  - We have not at all agreed to formal recognition of optional parts of
the standard.
   As a matter of fact, on the call there were more opinions expressed
in favor of
   use of a subset in a certain instant, not optional sections.  We may
at the end conclude
   that for some features optional is the best way, but have not gone
there yet. 
OK, I'll turn this into suggestion or drop it.
  - Optimization potential:  don't get into too much detail.  I am not
convinced that all
     that is listed there is actually correct - implementation can do
(and do) a lot to
     eliminate some of the things listed in the bulleted list. 
 I'll consider this.
  - What did you have in mind with "mutually incompatible families" ? 
Several stable combinations of subsets may emerge that will cover
different application areas well, but they (the subsets) will be
mutually incompatible between each other.

        Hi everybody,
        
        Thanks for your comments. Now the slides are also in the Wiki,
see
http://svn.mpi-forum.org/trac/mpi-forum-web/attachment/wiki/SubsettingWi
kiPage/MPI-3%20subsetting.ppt .
        
        Note that I'm going to incorporate your feedback and remove the
backup in the final version - we'll only have 5 minutes to present the
WG results to the Forum.
        
        Best regards.
        
        Alexander

        Hi everybody,
        
        Here come the promised draft slides for the subsetting
presentation at the MPI Forum. I put this into our corporate template, I
hope everybody is OK with this.
        
        Your comments will be most appreciated. I would like to finalize
the slides on Friday, so please send your feedback by EOD your time on
Thursday, March 6, 2008.
        
        Sorry for the message size. I cannot upload this file to the
Wiki due to file size limitation there. I work this with Rich in
background.
        
        Best regards.
